Hi everybody,

I'm looking for a program to combine more than 1.000 images into a single pdf file. Let me explain, I want to make a gift to my girlfriend, downloading and printing all her tumblr posts on a 700 x 100 cm paper. Yes you may argue what the hell is she going to do with a such big piece of paper. I don't know, but it will be funny.

any ideas about that kind of program?

thanks in advance

Adobe Acrobat is the specialist for Pdf.

I use Photoshop for creating Pdfs.

Open all of the documents in Preview, using a single pane with sidebar. In the sidebar pane, drag them into the desired order. When done, select all documents in the sidebar.

Go to Print. The command will have changed to Print Selected Images.

Click the PDF button on lower left. Save As PDF.

I probably wouldn't use Acrobat.
So you have a printable area of 7 m^2 (100 cm / 2.5 cm * inch = 40 inch; 40 inch * 150 dots/inch = 6000). At 150 dpi, this means you have ~252 megapixels to work with and the pdf you create will for sure be in the xxx MB range! I don't think it's a good idea going that route, I'd just save it as a jpg.

To be honest, you can probably use 120 dpi (depends on the printer/printing process) or even a little less. Since the number of pixels scales quadratically, even this `small' difference of 30 dpi will result in a picture that has ~90 MP less. (I had something printed on canvas last week and they used 120 dpi; however, due to the specific material (very rough) and the large viewing distance, you can easily get by with less dpi).

(1) The first order of business is to rescale all the photos. I recommend a command line tool called ImageMagick to do that. If you want to use, you only need 250,000 pixels per photo.
(2) I'd probably use software like MacOSaiX to generate a mosaic from, say, a picture of your gf using the 1000 images you have. Note that generating a picture of this size will be slow and take time! So resizing those 1000 pictures will be essential.

120 dpi? Thats coarse. Recommended resolution is 300dpi.

Mosaix!

MacOSaiX - Mosaics for Mac OS X it did a nice job.
